Audio Algorithm Support

Guidelines
2-60
The RMX supports the following audio algorithms: G.711, G. 719, G.722,
G.722.1, G. 728, G.729A, G.723.1, Siren14 and Siren 22.
Polycom's proprietary Siren 22 and industry standard G.719 audio
algorithms are supported for participants connecting with Polycom
endpoints.
The Siren 22 audio algorithm provides CD-quality audio for better clarity
and less listener fatigue with audio and visual communication
applications. Siren 22 requires less computing power and has much lower
latency than alternative wideband audio technologies.
• Siren 22, G.719 and Siren 22Stereo are supported with MPM+ and
MPMx cards.
• Siren 22 and G.719 are supported in both mono and stereo.
• Stereo is supported in H.323 calls only.
• Siren 22 is supported by Polycom HDX endpoints, version 2.0 and
later.
• G.728 is supported with both MPM+ and MPMx cards and in H.323,
SIP and ISDN environments.
